【摘要】：为实现隐伏陷落柱的预判与精确探查,确定了"地质预判、水质预警、物探定位、钻探控制"的综合探查措施:地质预判即通过水文地质条件和历史陷落柱致灾条件分析,总结出矿区陷落柱发育规律;水质预警即通过对出水点水量、水质、水温、水压的监测分析,确定水源;物探定位即通过"地面-井下"综合物探探查圈定了异常区域;钻探控制即采用定向钻探技术,准确控制陷落柱的空间形态及边界。通过上述综合方案的实施,实现了任楼煤矿Ⅱ51轨道大巷隐伏导水陷落柱的预判与超前精确探查。
[Abstract]:In order to realize the prediction and accurate exploration of concealed collapse columns, the comprehensive exploration measures of "geological prediction, water quality early warning, geophysical exploration positioning, drilling control" are determined: geological prejudgment is based on the analysis of hydrogeological conditions and historical collapse column disaster conditions. The development law of subsidence pillar in mining area is summarized, the water quality warning is to determine the source of water by monitoring and analyzing the quantity of water point, water quality, water temperature and water pressure, and the geophysical exploration positioning is to delineate the abnormal area through the comprehensive geophysical exploration of "surface-downhole". Drilling control is the use of directional drilling technology to accurately control the spatial shape and boundary of collapse columns. Through the implementation of the comprehensive scheme mentioned above, the prediction and the advanced accurate exploration of the concealed water guide and subsidence column in the 鈪，
